After 40, Your Muscles Need More Protein, Not More Gym Time

Most adults over 40 struggle to build or maintain muscle, even with regular exercise.
The reason is a cellular shift called Anabolic Resistance, your muscles become less responsive to smaller protein doses.

In your 20s, 20–25g of protein can trigger Muscle Protein Synthesis.
After 40, you often need 35–40g of high-quality protein per meal to activate the same repair and growth response.

This matters because muscle isn’t just for strength. It is the primary site for glucose disposal, and losing it increases the risk of insulin resistance, Pre-diabetes, and Sarcopenia.

If you feel you’re “doing everything right” but not seeing results, the issue may be metabolic, not motivational.
